pg.el is a socket-level interface to PostgreSQL for emacs (text
editor extraordinaire). The module is capable of type coercions from a
range of SQL types to the equivalent Emacs Lisp type. It currently
supports neither crypt or Kerberos authentication, nor large objects.
The code (version 0.2) is available under GNU GPL from
<URL:http://www.chez.com/emarsden/downloads/pg.el>
Changes since last release:
* now works with XEmacs (tested with Emacs 19.34 & 20.2, and XEmacs
20.4)
* added functions to provide database metainformation (list of
databases, of tables, of columns)
* arguments to `pg:result' are now :keywords
* MULE-resistant
* more self-testing code
Please note that this is a programmer's API, and doesn't provide any
form of user interface. Example:
(defun demo ()
(interactive)
(let* ((conn (pg:connect "template1" "postgres" "postgres"))
(res (pg:exec conn "SELECT * from scshdemo WHERE a = 42")))
(message "status is %s" (pg:result res :status))
(message "metadata is %s" (pg:result res :attributes))
(message "data is %s" (pg:result res :tuples))
(pg:disconnect conn)))
